Ion-Exchange (Ix): Arsenic And Chromium Removal From Brines And Removal Of Inorganic Contaminants By Specialty Resins, Behrang Pakzadeh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although ion exchange is highly efficient in removing inorganic contaminants, similar to other water treatment technologies, ion exchange has some drawbacks that need to be studied further. Three issues related to drawbacks of ion-exchange resins in water treatment were addressed in this research. The first issue was the influence of anionic inorganic co-contaminants including nitrate, Cr(VI), Se(VI), and As(V) on the performances of nitrate and perchlorate specialty (selective) resins in water treatment. It was found that nitrate can be removed from waters using perchlorate specialty resins, but the resin is poorly regenerated. Perchlorate was not easily removed from either nitrate …

Water Quality And Public Health Monitoring Of Surface Waters In The Kura-Araks River Basin Of Armenia, Azerbaijan, And Georgia, Amy Ewing

Water Resources Professional Project Reports

The Kura-Araks (sometimes spelled Aras) River Basin is an international river basin located in the South Caucasus with five separate countries contributing area to the watershed. These countries are Turkey, Iran, Armenia, Georgia, and Azerbaijan. Surface water from the Kura and Araks Rivers is used for a variety of uses, including municipal, agricultural, industrial, and mining, and the waste products from each of these uses are discharged back into the rivers. Many of the resulting contaminants pose significant risks to human health, including exposure to organic pollution derived from municipal use, organochlorine pesticides and high nitrate from agriculture, chemical contamination …

Sustainable Portland: Implementation Series 3, New England Environmental Finance Center

Climate Change

This report is the third in a series of efforts by students at the Muskie School of Public Service, Community Planning and Development Master’s program, in a core class called “Sustainable Communities.” In this course students seek to understand principles of sustainability and how efforts to implement Sustainability programs can become more successful. The report assembles term papers students completed on particular efforts by municipalities, universities, and other groups to achieve sustainability goals. Students worked on each project in a service learning format with real world clients. They were asked to fashion their papers around lessons learned by other organizations …

Regional Scarcity, Andrew Funk

Water Resources Professional Project Reports

The foreseeable vulnerability of regional water supplies in the Lower 48 to shortages from over stressed basins is made worse by anticipated water resource impacts from climate change. Essentially, regional water scarcity will differ depending on state and local supply and demand portfolios and variability of climate. Since U.S. water supply vulnerabilities are regionally uneven, the strategic water use efficiency response needs to be regional as well. Regionally mandatory water use efficiency should replace the outdated paradigm of voluntary measures currently employed piecemeal and unevenly within state borders, which ignore regional watershed hydrology. Mandating the efficient use of regional water …

Aquatic Fauna - Biological Survey Ten Mile Brook Dam Margaret River - Fisheries Research Contract Report No. 22, 2010, Craig Lawrence, C Hugh, Renae Larsen, J Ledger, Phil Vercoe

Fisheries Research Contract Reports

Ten Mile Brook Dam has a surface area of 275 Ha and receives water from a 10 km2 catchment (Figure 1). It has a total storage capacity of 1,691 ML. At the time of this study the dam was 89 % capacity (1,511 ML), however as recently as June 2009 water storage was as low as 663 ML (39 % capacity).

In order to improve the drinking water supply to the town of Margaret River, the Water Corporation is investigating the option of pumping bore water into Ten Mile Brook Dam. This would remove the need to transfer water from …

Integrated Water Resources Management: A Theoretical Exploration Of The Implementation Gap Between The Developed And Developing Worlds, Jennifer S. Schiff

Graduate Program in International Studies Theses & Dissertations

As part of its Millennium Development Goals, the United Nations acknowledges that solving the world's water woes requires giving one billion additional people access to safe and affordable drinking water, while also noting that this is a difficult goal to achieve considering present environmental challenges. Amidst this atmosphere of vanishing freshwater, the legislative policy community has begun to encourage diverse discourse on the topic of efficient resource management, but the form and function of such a solution present unique political and theoretical challenges for policymakers and scholars alike. The current consensus among water managers is that a multifaceted policy framework …

The Influence Of Mechanical Circulation On Water Column Stability And Dissolved Oxygen In Stratified Lakes, Paal Engebrigtsen

Civil & Environmental Engineering Theses & Dissertations

Surface circulators have been used in wastewater and industrial lagoons for many years, but only recently have they been designed for lakes and reservoirs as a water quality management tool. Their relatively low capital investment and operational costs make them an attractive chemical free option for ameliorating the symptoms of eutrophication. Little research has been conducted on their effectiveness in impacting water quality. Today many lake managers are waiting for independent research on surface circulators' performance before installing such systems.

The Occoquan Reservoir was the primary site for a study conducted to examine the influence of surface circulation on water …

Evaluation Of Alternative Technologies To Supply Drinking Water To Marines In Forward Deployed Locations, Derek R. George

Theses and Dissertations

With recent increases, there are approximately 20,000 Marines deployed in the Helmand Province of Afghanistan. The cost of delivering bottled water to the troops is rapidly becoming unsustainable and convoys delivering bottled water are vulnerable to Improvised Explosive Devices (IEDs). Currently, raw water from indigenous sources, which has chemical and microbiological contaminants, is treated with reverse osmosis (RO), but only used for hygiene, with bottled water used for drinking. Due to the economic costs and risks to life of providing bottled water, decision-makers need to evaluate technology alternatives to treat raw water to supply safe drinking water. In this study, …

Modeling The Fate Of Groundwater Contaminants Resulting From Leakage Of Butanol-Blended Fuel, Khai H. Vuong

Theses and Dissertations

Fuel spills and leaks from storage tanks can contaminate groundwater. Typically in groundwater, hazardous aromatic hydrocarbons like benzene are attenuated through natural processes. However, it is possible that adding butanol to gasoline will interfere with these natural attenuation processes, so that spills and leaks of alternative fuels containing biobutanol may result in more persistent hazardous aromatic hydrocarbon plumes. This effect has already been observed with ethanol, which is currently added to gasoline. A numerical model was developed to simulate the subsurface fate and transport of butanol-blended fuel to assess the potential impacts of butanol on the natural attenuation of benzene. …

Siltcoos Lake Nonpoint Source Implementation Grant: Water Quality Conditions And Nutrient Sources, Mark D. Sytsma, Rich Miller

Center for Lakes and Reservoirs Publications and Presentations

Siltcoos Lake is a large (1280 hectares), shallow (mean depth 3.3 m; maximum depth 6.7 m) lake located on the Central Oregon Coast, just south of Florence and bordered by Dunes City, Oregon. The outflow and water level of Siltcoos Lake is regulated by a dam on the Siltcoos River 4 km upstream from the Pacific. Several permanent streams feed the lake from its 176 square kilometer watershed including Fiddle Creek, Maple Creek, and Woahink Creek, the outflow from Woahink Lake. Much of the watershed is forested and used for timber harvest, residential development, and limited agricultural production.
